From your question I am perceiving that you parked straight and someone came and parked beside you but the rear of their car is blocking the rear of your car. You would be at fault because you should have realized that you wouldn't have been able to back out. In that case you should have contacted the local police (don't call 911) to have them do something with the car if you are not able to find the owner of the vehicle.
